Placeholder boot option and boot option replacement system

ABSTRACT

A boot option system includes a pre-boot execution environment system coupled to a server device through a network. The server device creates a device placeholder boot option including a device path terminating at a storage controller in the server device. During a first boot and based on first boot instructions received from the pre-boot execution environment system, the server device moves the device placeholder boot option to a desired location within a boot sequence for the server device. During a second boot and based on second boot instructions received from the pre-boot execution environment system, the server device provides an operating system on the server device. The server device then replaces, at the desired location within the boot sequence, the device placeholder boot option with an operating system boot option that was provided on the server device in response to the provisioning of the operating system on the server device.

BACKGROUND

The present disclosure relates generally to information handlingsystems, and more particularly to modifying boot options in a bootsequence for an information handling system.

As the value and use of information continues to increase, individualsand businesses seek additional ways to process and store information.One option available to users is information handling systems. Aninformation handling system generally processes, compiles, stores,and/or communicates information or data for business, personal, or otherpurposes thereby allowing users to take advantage of the value of theinformation. Because technology and information handling needs andrequirements vary between different users or applications, informationhandling systems may also vary regarding what information is handled,how the information is handled, how much information is processed,stored, or communicated, and how quickly and efficiently the informationmay be processed, stored, or communicated. The variations in informationhandling systems allow for information handling systems to be general orconfigured for a specific user or specific use such as financialtransaction processing, airline reservations, enterprise data storage,or global communications. In addition, information handling systems mayinclude a variety of hardware and software components that may beconfigured to process, store, and communicate information and mayinclude one or more computer systems, data storage systems, andnetworking systems.

Many information handling systems such as, for example, server devices,are now booted or otherwise initialize according to the UniversallyExtensible Firmware Interface (UEFI) specification. The UEFIspecification defines a process for automatically adding boot optionsfor a fixed disk or other fixed media (i.e., hard drives or otherstorage media that are internal to the chassis of the server device suchthat they cannot be easily removed.) For example, Boot Device Selection(BDS) code executed by the UEFI subsystem in the server device providesfor a determination of the presence of boot loader files (e.g., anEFI/Boot/BootX64.efi file) in a fixed disk included in the serverdevice, which requires boot loader files to be present in that fixeddisk in order for their associated boot options to be available.Conventional operating system installers operate to create a boot optionafter operating system installation, and then move that boot option tothe top of the boot sequence for the server device so that the serverdevice will automatically boot using that boot option on subsequentboots. Such conventional operations work well with local operatingsystem installation, but present issues with data centers that utilizePreboot Execution Environments (PXEs) that allow networked serverdevices that are not yet loaded with an operating system to beconfigured and booted remotely by a data center administrator. Forexample, a data center utilizing a PXE and server devices in a UEFI bootmode cannot operate according to the UEFI specification to setpredetermined boot orders in those server devices before an operatingsystem is installed, because there will not be a boot option for the forthe server device storage system (e.g., provided by Redundant Array ofIndependent Disk (RAID) volumes) prior to the operating systeminstallation.

Accordingly, it would be desirable to provide an improved boot optionmodification system.

SUMMARY

According to one embodiment, an Information Handling System (IHS)includes a storage controller; a processing system that is coupled tothe storage controller; and a memory system that is coupled to theprocessing system and that includes instructions that, when executed bythe processing system, cause the processing system to provide anUniversally Extensible Firmware Interface (UEFI) engine that isconfigured to: create a device placeholder boot option that includes adevice path terminating at a storage controller; move, during a firstboot and based on first boot instructions, the device placeholder bootoption to a desired location within a boot sequence; provide, during asecond boot that is subsequent to the first boot and based on secondboot instructions, an operating system on a storage system that iscoupled to the storage controller; and replace, at the desired locationwithin the boot sequence, the device placeholder boot option with anoperating system boot option that was provided on the storage system inresponse to the provisioning of the operating system.

It should be understood that other buses and intermediate circuitscan be deployed between the components described above and processor 102to facilitate interconnection between the components and the processor102.

Referring now to FIG. 2, an embodiment of a boot option modificationsystem 200 is illustrated. While the illustrated embodiment is describedas utilized with computing devices that operate in a UEFI boot mode, oneof skill in the art in possession of the present disclosure willrecognize that computing devices utilizing different types of a BasicInput/Output System (BIOS) may benefit from the teachings of the presentdisclosure and thus will fall within the scope of the present disclosureas well. In the illustrated embodiment, the boot option modificationsystem 200 includes a plurality of server devices 202 a, 202 b, and upto 202 c. In an embodiment, any or all of the server devices may beprovided by the information handling system 100 discussed above withreference to FIG. 1, and/or may include some or all of the components ofthe IHS 100. Furthermore, while illustrated and described as serverdevices, in some embodiments the server devices 202 a-c may be replacedby networking devices (e.g., switches), storage systems, desktopcomputing devices, laptop computing devices, and/or a variety of othercomputing devices that would be apparent to one of skill in the art inpossession of the present disclosure. Each of the server devices 202 a-cis coupled to a network 204, which in the embodiment discussed below isdescribed as being provided by a Local Area Network (LAN). However,other networks (e.g., wireless networks, the Internet, etc.) may beutilized in providing the network 204 while remaining within the scopeof the present disclosure as well.

In the illustrated embodiment, a Pre-boot eXecution Environment (PXE)system 206 is coupled to the network 204. As would be understood by oneof skill in the art in possession of the present disclosure, the PXEsystem 206 may include one or more servers that provide a client/serverenvironment (with the server devices 202 a-c acting as the clients, andthe PXE system 206 acting as the server) that is configured to allow theserver devices 202 a-c to receive a software assembly from the PXEsystem 206 through the network 204 and boot from that software assembly.As such, in order to boot, the server devices 202 a-c only require a PXEcapable Network Interface Controller (NIC), along with a relativelysmall set of industry-standard network protocols (e.g., the Dynamic HostConfiguration Protocol (DHCP), the Trivial File Transfer Protocol(TFTP), etc.) While one of skill in the art will recognize that the PXEis part of the UEFI standard and a common option for operating systembooting, installation, and deployment, other network-based bootenablement systems utilized with other BIOS-enabled computing devicesmay benefit from the teachings of the present disclosure and thus willfall within its scope as well. While a specific boot option modificationsystem 200 has been described, one of skill in the art in possession ofthe present disclosure will recognize that boot option modificationsystems may include other devices and/or other device configurationswhile remaining within the scope of the present disclosure as well.

Referring now to FIG. 3, an embodiment of a server device 300 isillustrated that may be any of the server devices 202 a-c discussedabove with reference to FIG. 2. As such, the server device 300 may beprovided by the IHS 100 discussed above with reference to FIG. 1, and/ormay include some or all of the components of the IHS 100. In theillustrated embodiment, the server device 300 includes a chassis 302that houses the components of the server device 300, only some of whichare illustrated in FIG. 3. For example, the chassis 302 may house aprocessing system (not illustrated, but which may include the processor102 discussed above with reference to FIG. 1) and a memory system (notillustrated, but which may include the memory 114 discussed above withreference to FIG. 1) that is coupled to the processing system and thatincludes instructions that, when executed by the processing system,cause the processing system to provide a UEFI engine 304 that isconfigured to perform the functions of the UEFI engines and serverdevices discussed below. In an embodiment, the UEFI engine 304 may beprovided by UEFI firmware that is configured to provide an interfacebetween an operating system (when that operating system is provided onthe server device 300) and server firmware and/or other hardware in theserver device 300. As discussed above, while the engine 304 isillustrated and described as a UEFI engine, one of skill in the art inpossession of the present disclosure will recognize that computingdevices utilizing different types of BIOS engines may benefit from theteachings of the present disclosure, and thus the engine 304 may beprovided by a BIOS engine or other processor/memory enabled engineswhile falling within the scope of the present disclosure as well.Furthermore, some functionality of the UEFI engine 304 discussed belowmay be performed by an operating system, or via cooperation between aUEFI/BIOS engine and an operating system, while remaining within thescope of the present disclosure.

The chassis 302 may also house a UEFI storage 306 that is coupled to theUEFI engine 304 (e.g., via a coupling between the processing system andthe UEFI storage 306). While illustrated as separate, one of skill inthe art in possession of the present disclosure will recognize that theUEFI storage 306 may be provided by a database or other data structurethat is included in the UEFI firmware while remaining within the scopeof the present disclosure. As discussed below, the UEFI storage 306 maystore a boot sequence for the server device 300 that includes bootoption(s), although the storage of other data and/or information in theUEFI storage 306 will fall within the scope of the present disclosure aswell. The chassis 302 may also house a communication subsystem 308 thatis coupled to the UEFI engine 304 (e.g., via a coupling between theprocessing system and the communication subsystem 308) and that, in theembodiments illustrated and discussed below, is provided by aPXE-enabled Network Interface Controller (NIC) that may be configured tocommunicate with the PXE system 206 (e.g., via DHCP, TFTP, etc.).However, other communication subsystems and/or components (e.g.,wireless communication subsystems such as BLUETOOTH®, Near FieldCommunication (NFC), etc.) may be utilized to provide the communicationssubsystem while remaining within the scope of the present disclosure.

The chassis 302 may also house a storage controller 309 that is coupledto the UEFI engine 304 (e.g., via a coupling between the processingsystem and the storage controller 309), and that may be provided by aRedundant Array of Independent Disks (RAID) controller or other storagedevice array controller that is configured to manage physical storagedevices and present them to the UEFI engine 304 (as well as an operatingsystem when that operating system is provided on the server device 300)as a virtual disk, logical units, and/or other disk array elements. Assuch, the storage controller 309 may include a disk cache, aninterconnect between the storage controller 309 and the server device300 (e.g., the Peripheral Component Interconnect (PCI) node on the RAIDstorage controller discussed below), and/or any other storage controllercomponents that would be apparent to one of skill in the art inpossession of the present disclosure. In the illustrated embodiment, thestorage controller 309 is illustrated as coupled to a storage subsystem310. In the embodiments discussed below, the storage subsystem 310 isprovided by a RAID storage subsystem including a plurality of storagedevices, although other storage systems and/or storage devices may fallwithin the scope of the present disclosure as well. Furthermore, asdiscussed below, in some embodiments the storage subsystem 310 may beprovided in the server device 300 and coupled to the storage controller309 during the method 400, and thus may not be included in the chassis302 at the beginning of the method 400. While a specific server device300 has been illustrated and described, one of skill in the art inpossession of the present disclosure will recognize that server devicesmay include different components and/or component configurations forproviding conventional server device functionality, as well as thefunctionality discussed below, while remaining within the scope of thepresent disclosure as well.

Referring now to FIG. 4, an embodiment of a method 400 for modifyingboot options is illustrated. As discussed below, some embodiments of thesystems and methods of the present disclosure do not follow the UEFIspecification and industry-standard methods for automatically creatingboot options for a fixed disk in a computing device based on thepresence of a boot loader file in that computing device, and rathercreate a device placeholder boot option for a fixed disk based on itsPCI device path, and provide that device placeholder boot option in adesired location in the boot sequence for the computing device.Subsequently, following the provisioning of an operating system on thecomputing device, the device placeholder boot option may be replaced (atthe desired location in the boot sequence) by an operating system bootoption that was provided on the computing device as a result of theprovisioning of the operating system. As described herein, suchfunctionality may be utilized to allow a user of a computing device tomanipulate a fixed disk boot option for that computing device prior to avirtual disk being created on a RAID storage system in that computingdevice. Furthermore, this functionality may be extended to create thevirtual disk on the RAID storage system in the computing device andmanipulate the fixed disk boot option for that computing device duringthe same boot operation.

The method 400 begins at decision block 402 where it is determinedwhether a device placeholder boot option is enabled for a server device.In some embodiments, prior to decision block 402, the UEFI storage 306may be provided with a system setup option for enabling the deviceplaceholder boot option of the present disclosure. For example, a systemsetup option such as “System BIOS→Boot Settings→Hard Disk DrivePlaceholder” may be available via the UEFI engine 304, and may beenabled by a manufacturer or user of the server device 300 that wishesto utilize the functionality described below. As such, prior to decisionblock 402, a manufacturer or user of the server device 300 may enablethe device placeholder boot option, or may leave the device placeholderboot option disabled if they wish to have the UEFI engine 304 operate ina conventional manner, also described briefly below. However, in someembodiments, the device placeholder boot option may be automaticallyenabled (i.e., by the manufacturer of the server device 300 such that itmust be disabled by a user of the server device 300 if that user wishesto have the UEFI engine 304 operate in a conventional manner).Furthermore, in yet other embodiments, the device placeholder bootoption may be configured such that it may not be disabled, in which casedecision block 402 and block 404 may be omitted from the method 400.Thus, at decision block 402 and in embodiments where the deviceplaceholder boot option is configured to be enabled and/or disabled, theUEFI engine 304 may operate to determine whether the device placeholderboot option is enabled in the UEFI storage 306. For example, upon anyboot of the server device 300 (e.g., the first PXE boot that is part ofthe PXE boot 1 phase and the second PXE boot that is part of the PXEboot 2 phase, discussed in further detail below), the UEFI engine 304 orother BIOS engine may perform decision block 402 to determine whetherthe device placeholder boot option is enabled by detecting a persistentsetting in non-volatile memory that was set during the CFI phase andthat enables the device placeholder boot option.

If, at decision block 402, it is determined that the device placeholderboot option is not enabled for the server device, the method 400 thenproceeds to block 404 where the UEFI engine performs conventional bootoperations. One of skill in the art in possession of the presentdisclosure will recognize that the UEFI engine 304 may perform a varietyof conventional UEFI boot operations at block 404, and thus thoseconventional boot operations are not described in detail herein.

However, referring now to FIG. 5, a prior art boot process flow 500 isillustrated to provide an example of how a conventional boot process(which may be performed at block 404) may be limited for at least someof the reasons discussed above. In particular, the prior art bootprocess flow 500 illustrates how a conventional boot process may operateto prevent the positioning of a RAID boot option for the RAID storagesubsystem 310 behind NIC boot option(s) for the communication subsystem308 in the boot sequence of the server device 300, which may bedesirable for server devices included in data centers that utilize PXEsystems. In the illustrated embodiment, the boot process flow 500includes a phase section 502 that details different phases of a specificboot process that includes a Custom Factory Integration (CFI) phase, anout-of-box phase, a PXE boot 1 phase, an end-of-PXE-boot-1 phase, a PXEboot 2 phase, and an end-of-PXE-boot-2 phase. One of skill in the art inpossession of the present disclosure will recognize that theconventional boot process illustrated by the prior art boot process flow500 is a two PXE boot process that includes a first boot (via a PXEsystem) for providing a hardware configuration on the server device 300,and a second boot (via the PXE system) for installing an operatingsystem in the server device 300, and that other conventional bootprocesses will include different phases and/or omit some of the phasesillustrated in FIG. 5. The boot process flow 500 also includes a processsection 504 that describes processes occurring during the conventionalboot process at each of the CFI phase, the PXE boot 1 phase, and the PXEboot 2 phase; as well as a boot sequence section 506 that provides theboot sequence for the server device at each of the out-of-box phase, theend-of-PXE-boot-1 phase, and the end-of-PXE-boot-2 phase.

As illustrated in FIG. 5, at the CFI phase the RAID storage subsystem310 in the server device 300 may be configured by, for example,configuring a virtual disk in the RAID storage subsystem 310. Asdiscussed above, following the CFI phase and at the out-of-box phase,the boot sequence 506 will only include a NIC 1 boot option for aPXE-enabled NIC (“NIC.Integrated.1-1-1”) due to, for example, thecommunication subsystem 308 being the only bootable device in the serverdevice 300 at this phase. At the PXE boot 1 phase, a first PXE boot isperformed via the PXE system 206 and through the network 204, and thatfirst PXE boot may be performed via the execution of a script set (e.g.,including racadm/syscfg scripts) that provides for the configuration ofhardware in the server device 300. As illustrated in FIG. 5, during thePXE boot 1 phase, a second PXE boot (discussed below) is enabled. FIG. 5also illustrates how an attempt to set a RAID boot option for the RAIDstorage subsystem 310 behind the NIC 1 boot option for the PXE-enabledNIC will fail (as illustrated by element 508) because the RAID bootoption is not present in the boot sequence for the server device 300 atthe PXE boot 1 phase (i.e., the NIC 1 boot option for the PXE-enabledNIC is the only device boot option currently in the boot sequence forthe server device 300 at this point in the boot process.) The PXE boot 1phase ends when a reboot is performed, and at the end-of-PXE-boot-1phase, the boot sequence 506 will include a NIC 2 boot option for thePXE-enabled NIC in addition to the NIC 1 boot option for the PXE-enabledNIC (e.g., a “NIC.Integrated.1-2-1” that was added to the boot sequenceas part of the enablement of the second PXE boot during the PXE boot 1phase, in addition to the “NIC.Integrated.1-1-1” that was part of theboot sequence at the out-of-box phase.)

At the PXE boot 2 phase, a second PXE boot (enabled during the PXE boot1 phase, discussed above) is performed via the PXE system 206 andthrough the network 204, and that second PXE boot may be performed viathe execution of a script set (e.g., including racadm/syscfg scripts)that provides for the installation of an operating system on the serverdevice 300. As illustrated in FIG. 5, during the PXE boot 2 phase anoperating system is installed, and the PXE boot 2 phase ends when areboot is performed. At the end-of-PXE-boot-2 phase, the boot sequence506 will include a RAID boot option for the RAID storage subsystem 310positioned ahead of the NIC 1 boot option and the NIC 2 boot option forthe PXE-enabled NIC (e.g., the “NIC.Integrated.1-1-1” and the“NIC.Integrated.1-2-1”.) As discussed above, this positioning of theRAID boot option (i.e., in front of the NIC 1 boot option and the NIC 2boot option) is due to the conventional operating system installerperforming conventional operations to create the RAID boot option forthe RAID storage subsystem 310 as part of the operating systeminstallation, and move that RAID boot option to the top of the bootsequence so that the server device 300 will automatically boot usingthat RAID boot option on subsequent boots. However, FIG. 5 illustratesthe RAID boot option at the top of the boot sequence 506 as a failure(as illustrated by element 510), as the implementation of the PXE system206 in this embodiment makes it desirable to position the RAID bootoption behind the NIC 1 boot option and the NIC 2 boot option in theboot sequence of the server device 300. Thus, conventional boot processflows result in failures (examples of which is detailed above)associated with desirable functionality for PXE systems.

If, at decision block 402, it is determined that the device placeholderboot option is enabled for the server device, the method 400 thenproceeds to block 406 where the UEFI engine creates a device placeholderboot option. In an embodiment, at block 406, the UEFI engine 304 mayoperate to create a device placeholder boot option in the UEFI storage306. For example, at block 402 the UEFI engine 304 may determine thatthe device placeholder boot option was enabled (e.g., during the CFIphase by the manufacturer of the server device 300 and, at block 406 andduring a boot of the server device 300 (e.g., the first PXE boot duringthe PXE boot 1 phase discussed in further detail below, the UEFI engine304 may create a boot option for the storage controller 309 (e.g., aRAID controller boot option, a hard disk controller boot option, etc.)that includes a device path that terminates at the storage controller309 (e.g., the device placeholder boot option may point to a device paththat terminates at a PCI node in the storage controller 309). Asdiscussed in further detail below, and as will be appreciated by one ofskill in the art in possession of the present disclosure, the deviceplaceholder boot option including a device path that terminates at a PCInode in the storage controller 309 allows for the creation of a bootoption based simply on the presence of the storage controller 309 in theserver device 300, and does not require the presence of the storagesubsystem 310 in the server device 300.

Referring now to FIG. 6, a boot process flow 600 according to theteachings of the present disclosure is illustrated. In particular, theboot process flow 600 illustrates how a boot process according to theteachings of the present disclosure may operate to allow the positioningof a RAID boot option for the RAID storage subsystem 310 behind NIC bootoption(s) for the communication subsystem 308 in the boot sequence ofthe server device 300 when the RAID storage subsystem 310 has alreadybeen configured in the server device 300, which may be desirable forserver devices included in data centers that utilize PXE systems.Similarly as discussed above with reference to the conventional bootprocess flow 500 of FIG. 5, the boot process flow 600 includes a phasesection 602 that details different phases of a specific boot processthat includes a Custom Factory Integration (CFI) phase, an out-of-boxphase, a PXE boot 1 phase, an end-of-PXE-boot-1 phase, a PXE boot 2phase, and an end-of-PXE-boot-2 phase. One of skill in the art inpossession of the present disclosure will recognize that the bootprocess illustrated by the boot process flow 600 is a two PXE bootprocess that includes a first boot (via a PXE system) for providing ahardware configuration on the server device 300, and a second boot (viathe PXE system) for installing an operating system in the server device300, and that boot processes according to the teaching of the presentdisclosure may include different phases and/or omit some of the phasesillustrated in FIG. 6. The boot process flow 600 also includes a processsection 604 that describes processes occurring during the boot processat each of the CFI phase, the PXE boot 1 phase, and the PXE boot 2phase; as well as a boot sequence section 606 that provides the bootsequence for the server device at each of the out-of-box phase, theend-of-PXE-boot-1 phase, and the end-of-PXE-boot-2 phase.

As illustrated in FIG. 6, at the CFI phase the RAID storage subsystem310 in the server device 300 may be configured by, for example,configuring a virtual disk in the RAID storage subsystem 310. Followingthe determination at block 402 that the device placeholder boot optionis enabled for the server device 300, the UEFI engine 304 operates tocreate the RAID placeholder boot option at block 406. As illustrated inFIG. 6, following the CFI phase and at the out-of-box phase, the bootsequence 606 will include a NIC 1 boot option for a PXE-enabled NIC(“NIC.Integrated.1-1-1”) due to, for example, the communicationsubsystem 308 being a bootable device in the server device 300 at thisphase, along with the RAID placeholder boot option positioned in frontof the NIC 1 boot option in the boot sequence 606.

Referring now to FIG. 7, a boot process flow 700 according to theteachings of the present disclosure is illustrated. In particular, theboot process flow 700 illustrates how a boot process according to theteachings of the present disclosure may operate to allow the positioningof a RAID boot option for the RAID storage subsystem 310 behind NIC bootoption(s) for the communication subsystem 308 in the boot sequence ofthe server device 300 prior to the configuration of the RAID storagesubsystem 310 in the server device 300, which may be desirable forserver devices included in data centers that utilize PXE systems.Similarly as discussed above with reference to the boot process flows500 and 600 of FIGS. 5 and 6, respectively, the boot process flow 700includes a phase section 702 that details different phases of a specificboot process that includes an out-of-box phase, a PXE boot 1 phase, anend-of-PXE-boot-1 phase, a PXE boot 2 phase, and an end-of-PXE-boot-2phase. One of skill in the art in possession of the present disclosurewill recognize that the boot process illustrated by the boot processflow 700 is a two PXE boot process that includes a first boot (via a PXEsystem) for providing a hardware configuration on the server device 300,and a second boot (via the PXE system) for installing an operatingsystem in the server device 300, and that boot processes according tothe teaching of the present disclosure may include different phasesand/or omit some of the phases illustrated in FIG. 7. The boot processflow 700 also includes a process section 704 that describes processesoccurring during the boot process at each of the PXE boot 1 phase andthe PXE boot 2 phase; as well as a boot sequence section 706 thatprovides the boot sequence for the server device at each of theout-of-box phase, the end-of-PXE-boot-1 phase, and the end-of-PXE-boot-2phase.

Following the determination at block 402 that the device placeholderboot option is enabled for the server device 300, the UEFI engine 304operates to create the RAID placeholder boot option at block 406. Asillustrated in FIG. 7, following the out-of-box phase, the boot sequence706 will include a NIC 1 boot option for a PXE-enabled NIC(“NIC.Integrated.1-1-1”) due to, for example, the communicationsubsystem 308 being a bootable device in the server device 300 at thisphase, along with the RAID placeholder boot option positioned in frontof the NIC 1 boot option in the boot sequence 706. Thus, the RAIDplaceholder boot option may be created at block 406 and provided in theboot sequence 706 for the server device 300 prior to the configurationof the RAID storage subsystem 310 (e.g., prior to the configuration of avirtual disk on the RAID storage subsystem 310.) Furthermore, one ofskill in the art in possession of the present disclosure will recognizethat device placeholder boot options may be created at block 406 andprovided in the boot sequence 706 prior to the connection or coupling ofthe storage subsystem 310 to the storage controller 309 in the serverdevice 300, and/or prior to the provisioning of a boot loader file inthe server device 300 (e.g., the provisioning of an EFI file, a bootfile, a BootX64.efi file, and/or other boot loader files in anon-removable BlockIO device that is published by the storage subsystem310.)

The method 400 then proceeds to block 408 where the UEFI engine movesthe device placeholder boot option to a desired location in a bootsequence. In an embodiment, at block 408, the UEFI engine 304 mayoperate to move the device placeholder boot option to a desired locationin a boot sequence for the server device 300 during a first boot of theserver device 300 that is based on first boot instructions. In theembodiments discussed below, the first boot instructions that providefor the first boot of the server device 300 are received through thenetwork 204 from the PXE system 206. However, one of skill in the art inpossession of the present disclosure will recognize that the first bootinstructions may be received in a variety of different manners (e.g.,the first boot instructions may be received from a removable storagedevice (e.g., a Universal Serial Bus (USB) device) coupled to the serverdevice 300, and/or other storage devices capable of storing the firstboot instructions) while remaining within the scope of the presentdisclosure as well.

With reference to the boot process flow illustrated in FIG. 6, the firstboot of the server device 300 may be a first PXE boot that occurs at thePXE boot 1 phase via the PXE system 206 and through the network 204, andthe first PXE boot may be performed via the execution of a script set(e.g., including racadm/syscfg scripts) that provides for theconfiguration of hardware in the server device 300. As illustrated inFIG. 6, during the PXE boot 1 phase, a second PXE boot (discussed below)is enabled. At block 408, the UEFI engine 304 operates to move the RAIDplaceholder boot option behind the boot option(s) for the communicationsubsystem 308 in the boot sequence 606 for the server device 300, whichdoes not result in a failure (as detailed with reference to FIG. 5above) because the RAID placeholder boot option is present in the bootsequence at this phase of the boot process. While the device placeholderboot option is illustrated and described as being positioned last nightthe boot sequence 606 for the server device 300 in this PXE systemembodiment, one of skill in the art in possession of the presentdisclosure will recognize that the device placeholder boot option may bepositioned at any desired location in the boot sequence 606 of theserver device 300 while remaining within the scope of the presentdisclosure. The PXE boot 1 phase ends when a reboot is performed, and atthe end-of-PXE-boot-1 phase, the boot sequence 606 will include a NIC 2boot option for the PXE-enabled NIC in addition to the NIC 1 boot optionfor the PXE-enabled NIC (e.g., a “NIC.Integrated.1-2-1” that was addedto the boot sequence as part of the enablement of the second PXE bootduring the PXE boot 1 phase, in addition to the “NIC.Integrated.1-1-1”that was part of the boot sequence at the out-of-box phase), along withthe RAID placeholder boot option positioned behind each of the NIC 1boot option and the NIC 2 boot option.

With reference to the boot process flow illustrated in FIG. 7, the firstboot of the server device 300 may be a first PXE boot that occurs at thePXE boot 1 phase via the PXE system 206 and through the network 204, andthe first PXE boot may be performed via the execution of a script set(e.g., including racadm/syscfg scripts) that provides for theconfiguration of hardware in the server device 300. As illustrated inFIG. 7, during the PXE boot 1 phase, a second PXE boot (discussed below)is enabled. At block 408, the UEFI engine 304 operates to move the RAIDplaceholder boot option behind the boot option(s) for the communicationsubsystem 308 in the boot sequence 606 for the server device 300, whichdoes not result in a failure (as detailed with reference to FIG. 5above) because the RAID placeholder boot option is present in the bootsequence at this phase of the boot process. While the device placeholderboot option is illustrated and described as being positioned last nightthe boot sequence 706 for the server device 300 in this PXE systemembodiment, one of skill in the art in possession of the presentdisclosure will recognize that the device placeholder boot option may bepositioned at any desired location in the boot sequence 706 of theserver device 300 while remaining within the scope of the presentdisclosure. In addition, at the PXE boot 1 phase, the RAID storagesubsystem 310 may be configured by configuring a virtual disk in theRAID storage subsystem 310, an operation that may be performedsubsequent to the creation of the RAID boot option and the positioningof the RAID boot option in the desired location in the boot sequence 706for the server device 300. The PXE boot 1 phase ends when a reboot isperformed, and at the end-of-PXE-boot-1 phase, the boot sequence 706will include a NIC 2 boot option for the PXE-enabled NIC in addition tothe NIC 1 boot option for the PXE-enabled NIC (e.g., a“NIC.Integrated.1-2-1” that was added to the boot sequence as part ofthe enablement of the second PXE boot during the PXE boot 1 phase, inaddition to the “NIC.Integrated.1-1-1” that was part of the bootsequence at the out-of-box phase), along with the RAID placeholder bootoption positioned behind each of the NIC 1 boot option and the NIC 2boot option.

The method 400 then proceeds to block 410 where the UEFI engine providesan operating system on the storage device. In an embodiment, at block410, the UEFI engine 304 may operate to provide an operating system onthe server device 300 during a second boot of the server device 300 thatis based on second boot instructions. In the embodiments discussedbelow, the second boot instructions that provide for the second boot ofthe server device 300 are received through the network 204 from the PXEsystem 206. However, one of skill in the art in possession of thepresent disclosure will recognize that the second boot instructions maybe received in a variety of different manners (e.g., the second bootinstructions may be received from a removable storage device (e.g., aUniversal Serial Bus (USB) device) coupled to the server device 300,and/or other storage devices capable of storing the second bootinstructions) while remaining within the scope of the present disclosureas well.

With reference to the boot process flows illustrated in FIGS. 6 and 7,the second boot of the server device 300 may be a second PXE boot thatoccurs at the PXE boot 2 phase via the PXE system 206 and through thenetwork 204, and the second PXE boot may be performed via the executionof a script set (e.g., including racadm/syscfg scripts) that providesfor the performance of an operating system installation process thatprovides for the installation of an operating system in the serverdevice 300. However, in other embodiments, the operating system may beprovided on the server device 300 as part of an operating system copyingprocess (e.g., as part of a General Hardware-Oriented System Transfer(GHOST) process and/or other disk cloning process that would be apparentto one of skill in the art in possession of the present disclosure)while remaining within the scope of the present disclosure as well. Asillustrated in FIGS. 6 and 7, during the PXE boot 2 phase, an operatingsystem is provided on the server device 300. For example, in embodimentsin which the operating system is installed on the server device 300, atblock 410 an operating system installer may create a RAID boot optionfor the RAID storage system 310 which, as discussed above, isconventionally positioned at the stop of the boot sequence 606 for theserver device 300. In another example, in embodiments in which theoperating system is copied to the server device 300 (e.g., via the GHOSTprocess or other disk cloning process discussed above), at block 410 theUEFI engine 304 (or other BIOS engine) may create boot loader file bootoption pointing to a boot loader file (e.g., BootX64.efi) that wascopied to the server device 300.

The method 400 then proceeds to block 412 where the UEFI engine replacesthe device placeholder boot option with an operating system boot option.In an embodiment, at block 412, the UEFI engine 304 operates to replacethe device placeholder boot option with an operating system boot optionthat was provided on the server device 300 in response to theprovisioning of the operating system on the server device 300. Asdiscussed above, in embodiments in which the operating system isinstalled on the server device 300, an operating system installer maycreate a RAID boot option for the RAID storage system 310. Withreference to FIGS. 6 and 7, at block 410 the UEFI engine 304 may replacethe RAID placeholder boot option with the operating-system-created RAIDboot option such that the operating-system-created RAID boot option islocated in the desired location in the boot sequence 606/706 in whichthe RAID placeholder boot option was positioned at block 408 (e.g.,behind each of the NIC 1 boot option and the NIC 2 boot option in theillustrated embodiment.) As also discussed above, in embodiments inwhich the operating system is copied to the server device 30, the UEFIengine 304 (or other BIOS engine) may create a boot loader file bootoption pointing to a boot loader file. With reference to FIGS. 6 and 7,at block 410 the UEFI engine 304 may replace the RAID placeholder bootoption with the UEFI/BIOS-engine-created boot loader file boot optionsuch that the UEFI/BIOS-engine-created boot loader file boot option islocated in the desired location in the boot sequence 606/706 in whichthe RAID placeholder boot option was positioned at block 408 (e.g.,behind each of the NIC 1 boot option and the NIC 2 boot option in theillustrated embodiment.)

Thus, systems and methods have been described that provide for thecreation of a RAID placeholder boot option for a RAID based on itsdevice path (e.g., pointing to a PCI node in its RAID storagecontroller), and provide that RAID placeholder boot option in a desiredlocation in the boot sequence for the server device. Subsequently,following the provisioning of an operating system on the server device,the RAID placeholder boot option may be replaced (at the desiredlocation in the boot sequence) by an operating system boot option thatwas provided on the server device as a result of the provisioning of theoperating system. Such functionality may be utilized to allow a user ofa server device to manipulate a fixed disk boot option for that serverdevice prior to a virtual disk being created on the RAID storage systemin that server device, which provides for the omission of a serverdevice reboot in both local (e.g., USB device enabled) and remote (e.g.,via scripts provided from a PXE system) operating system installations.Furthermore, this functionality may be extended to create the virtualdisk on the RAID storage system in the server device and manipulate thefixed disk boot option for that server device during the same bootoperation.
